Secrets

 * 1) After going through the first door and up the first staircase, you will see a switch on your left. This opens a door outside (visible through the window) leading to a heavy weapon dude and three armor bonuses. The north-eastern wall of this area is a secret door leading to a heavy weapon dude and a backpack. (sector 117)
 * 2) The passageway west of the blue door has several short green pillars lining the walls. The south-eastern one, which has a beating heart on top, marks a secret door leading (via a lift) to a room with a super shotgun plus several monsters and ammo. The structure in the middle of this room has a secret door in the southern alcove, leading to a Hell knight, a megasphere, and a switch. The switch opens up doors in the north-west and north-east of this area, revealing areas each containing 1-3 demons as well as some ammo. (sector 114)
 * 3) North of the switch which raises the stairs to the exit is a corridor whose northern side has a secret door (marked with a greenish texture) leading to an outdoor area with a large pyramid. The south-eastern part of the blood moat surrounding this area has a section of fake wall, behind which are three armor bonuses, two stimpacks, a backpack, an energy cell pack, and (on multiplayer) a rocket. (sector 71)
 * 4) Entering #3 causes the steps of the pyramid to rise and fall, allowing access to the top, which contains a red key (necessary for exiting this area), a soul sphere and a megaarmor. (sector 53)
 * 5) West of the switch which raises the stairs to the exit is a section of wall which lacks the greenish texture of the surrounding walls.  This is a secret door leading to an area with a computer map, some monsters, and other items, including (through a secret door to the west) a yellow key which is necessary to leave this area. There are two secrets here. (sector 61)
 * 6) See #5. (sector 73)
